Lochinvar L-CGN275100A Commercial Gas Water Heater 275K Btu

Product Description

The LOCHINVAR L-CGN275100A is a self-cleaning commercial gas water heater rated at 275,000 BTU/h with a nominal capacity of 100 gallons (98 gallons rated storage volume). It runs on natural gas with intermittent electronic ignition, eliminating the standing pilot to reduce fuel consumption. The unit features a glass-lined tank with multiple anode rods, each with a stainless steel core, to resist corrosion and extend service life. A factory-installed, CSA-certified, ASME-rated T and P relief valve is included. The self-cleaning system activates when cold water enters through the front connection, reducing sediment accumulation and maintaining rated thermal efficiency at 80 percent. Licensed plumbers and commercial HVAC technicians are the primary installers.

This water heater is designed for indoor commercial applications including new construction and replacement projects. Its compact, low-profile design is up to one foot shorter than the models it replaces. Inlet and outlet connections are located at the top, front, and rear, providing flexibility for tight mechanical rooms. The unit can be installed standalone, manifolded with other units, or connected to external storage tanks, making it adaptable to a range of commercial hot water system configurations.
